Specification of Letters Patent.

Patented April 13, 1909.

Application filed June 20, 1908. Serial No. 439,559.

' Be it known that I, FRANKT. TALOOTT, a citizen of the United States, residing at Ashtabula, in the county of Ashtabula and State of Ohio, have invented a new and useful Lubricating Apparatus, of which the followin 'is a specification.

y invention relates to im rovements in lubricatingapparatus for inc osed mechanism, and particularly to lubricating ap aratus for airpumps and compressors for l uids, andmy object is to provide means whereby in a pump or compressor the moving piston and the interior of the cylinder may be lubricated by oil or other lubricants atomized and forced into the cylinder under pressure created by the forward movement of the piston and whereby the lubricant used may be continuously so introduced at a redetermined rate, if so desired, so long as t 1e piston is in'motion and the pump or compressor is therefore in action, and will automatically cease when the pump or compressor stops.

In the drawings accompanying this specification Figure 1 is a sectional elevation of a power air pump eqluipped with my device, and Fig. 2 is a simi ar sectional elevation of an air pump equipped with a modified form of my Similar numerals refer to similar parts in evice.

the several figures. The reservoir for lubricant 10 is shown in cylindrical form and is rovided at the top and bottom respectivey with filling and cleaning openings 11 and 12. At the side of thereservoir 10 18 shown a gage glass 13.

Leading from a point 9 on the discharge 8 of the compressor cylinder 7 is a pipe 15 opening into the upper portion of the reservoir 10. This ip'e carries fluid from the dischar e 8 to the reservoir 10 under pressure induced by the forward movement of the piston 6 and is preferably equipped with a regulating valve 16 to regulate the fluid pressure upon the lubricant contained in the reservoir 10 and a check valve 36 to prevent back pressure.

' Leading from a point within the reservoir I '10, near the bottom of the reservoir and below the surface of the lubricant contained in the casing, is a discharge pipe 17 extending connected to an extension 1901? said pipe 17. The extension 19 connects with a discharge pipe 20 which leads to the intake 5 in the upper portion of the cylinder 7 of the compressor. The discharge pipe 20 carries fluid underpressure induced by the forward motion of the piston 6. Preferably a sight glass 22 is coupled in the pipe 19 and the pipe terminates in a drip nozzle 23 in the upper portion of the sight .in Fig. 1, a discharge pipe 30 which passes through the bottom of the reservoir 10 and is connected to the pipe 20 and is furnished, at the point of connection with pipe 20,with a suitable valve 35 by means of which the fluid pressure in the pipe 20 may be controlled. From a nozzle 4 is prefera lg extended through the pipe 20 to a point eyond the intersection of the extension 19 and the pipe 20 for the purpose of atomizing the lubricant as it drips through the sight glass 22 and the extension 19 to the pipe 20. Preferably, a check valve 3 is placed in the ipe 19 and a check valve 21 in the pipe 20 eyond its interseo tion with the extension 19.

In the modified form of my invent-ion shown in Fig. 2 a pipe 2 leads directly from a point on the discharge 15 of the compressor cylinder 7 to a valve 14, which valve 14 controls the flow of fluid from the pipe 15 to thepipe-ZO. The pipe 2, it will be seen, passes rn'tii'olv outside the reservoir 10. In this form ofiny device the ipe 2 is preferably equipped with a check va ve 18. The pipe-2 may load from any point on the fluid supply between the discharge 9 and the valve 16. Any device for atomizing the lubricant may be placed in the pipe 20 instead of the contracted nozzle shown in the drawing.

In operation the pressure on the lubricant in the reservoir 10 1s fixed and adjusted by the use of the valve 16, the rate of the drip of the lubricant through the sight glass 22 and the extension 19 is fixed by setting the valve 24, and the pressure in the pipe 20 is fixed by setting the valve 35, the pressure in the pi e 20 being made at the outset higher than t at in the extension 19 and thediflerence so fixed being maintained by the action of the check valves shown. During operation the rate of lubrication can be increased oint near the valve 35 a .lOU
